Abstract

Internet of Things (IoT) event objects can be tailored to specific device types and capabilities. An IoT event object can use a flexible definition of an event that can be reconfigured. An IoT event object allows for the ability to set different triggering conditions and priorities. Individual event definitions can be extended to create more complex events. A Notification Handler supports sending a request or command in response to an event that requires action.

Claims

1. In an Internet of Things network including an Internet of Things device, a method comprising:

determining, at the Internet of Things device, that conditions of an event expression defined in an event object have been met, the event expression using a value from at least one resource in the Internet of Things network; and

responsive to determining that the conditions of the event expression have been met, producing an indication that the conditions of the event expression have been met.

2. The method of claim 1, wherein the event object includes an event definition including the event expression.

3. The method of claim 2, wherein the event object includes multiple event definitions.

4. The method of claim 3, wherein more than one of the event definitions are combined into a complex event expression.

5. The method of claim 2, wherein the event definition includes a trigger condition that indicates how to obtain resource data for the expression.

6. The method of claim 2, wherein the event definition includes a trigger priority that indicates when to obtain resource data for other resources for the expression after the value from at least one resource is obtained and partially meets the requirements of the expression.

7. The method of claim 1, wherein the event object includes a control handler that includes a state value that indicates how the event is to be evaluated.

8. The method of claim 1, wherein the event object includes a notification handler that indicates what happens when an expression evaluates as true.

9. The method of claim 1, wherein the event object includes object info that indicates what event functionalities are supported by the device.

10. The method of claim 1, wherein the event object is part of a service layer.

11. A device comprising a processor and a memory storing computer executable instructions which when executed by the processor cause the processor to:

evaluate an event expression defined in an event object, the event expression using a value from at least one resource in an Internet of Things network, and

if the conditions of the expression have been met, produce an indication that conditions of the event expression have been met.

12. The device of claim 11, wherein the event object includes an event definition including the event expression.

13. The device of claim 12, wherein the event object includes multiple event definitions.

14. The device of claim 13, wherein more than one of the event definitions are combined into a complex event expression.

15. The device of claim 12, wherein the event definition includes a trigger condition that indicates how to obtain resource data for the expression.

16. The device of claim 12, wherein the event definition includes a trigger priority that indicates when to obtain resource data for other resources for the expression after the value from at least one resource is obtained and partially meets the requirements of the expression.

17. The device of claim 11, wherein the event object includes a control handler that includes a state value that indicates how the event is to be evaluated.

18. The device of claim 11, wherein the event object includes a notification handler that indicates what happens when an expression evaluates as true.

19. The device of claim 11, wherein the event object includes object info that indicates what event functionalities are supported by the device.

20. The device of claim 11, wherein the event object is part of a service layer.
